6 Claims.

This invention relates to new and useful improvements in a shirt collar band edge trimmer and notching machine.

The invention has for an object the construction of a device as mentioned which is characterized by an arrangement adapted to notch shirt collar bands and then to trim these bands. The purpose of notching the bands is to provide guide marks so that the bands Will be properly attached to shirts.

A further object of the invention is to provide an arrangement wherein the notching mechanism is resiliently supported and arranged to be moved into operative position to first notch the collar band, and an arrangement which causes die sections to function to trim the collar band.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of thisdisclos'ure:

Fig. 1 is a plan View of a machine constructed according to this invention.

Fig. 2 is a front elevational view of Fig. 1.

Fig. 3 is an end elevational view of Fig. 2 looking from the right hand end. 7

Fig. 4 is a sectional view taken on the line 4-4 of Fig.2.

Fig. 5 is a fragmentary enlarged detailed view of a portion of Fig. 4.

Fig. 6 shows a notched collar band resting upon the lower die section.

Fig. 7 shows another type of notched collar band resting upon the lower die section.

Fig 8 is a plan view of a lower die section constructed according to a modification.

The shirt collar band edge trimmer and notching machine includes a pair of spaced members It] and H which are slidably supported. A resilient means is provided for holding these members in a normally raised position. A pair of notching elements I2 and I3 are pivotally supported upon the members I [I and II. A means is provided for pivoting the elements I2 and I3 together and into operative positions and includes a toggle construction I4. A die section I5 is arranged beneath the elements I2 and I3 and is cooperative with a complementary die section It arranged between the elements I2 and. I3 and the elements I2 and I3. A means is provided 1936, Serial No. 87,884

for moving the complementary die section downwards into engagement with the die section I5.

The spaced members Ill and II are each supported upon a rod [1 which engages through slots I8 in vertical posts I8. are mounted upon a base plate I9. The slots Ill extend in from the top ends of the posts and terminate above the bottom ends. The upper portions of the posts are threaded. Nuts I9 engage upon the upper ends of the posts and form abutments for springs which have abutment strips 2i] attached on their top ends. These springs act against the rods I! and are opposed to other springs 2| also acting against the rods but located beneath the rods. It is the springs 20 and M which resiliently support the rods IT. The outer ends of the rods H are provided with heads 22 to prevent their disengagement from the posts I8. The springs 20 and 2| are so set that the members II) and II are held in a normally raised position.

The notching elements I2 and I3 each have pivots 23 on the top edges thereof engaging through the members III and II. It is these pivots which pivotally support the notching elements.

The notching elements are in the form of fiat plates, and upon the lower edges supporting notching pins 25. These notching pins are removable by reason of engaging into sockets 26 mounted on the plates. Screws 2'I cooperate with the sockets: in releasably holding the pins 25.

Between the notching elements I2 and I3 and at each of the ends there is the toggle construction Iii. Each toggle construction comprises a pair of pivotally connected levers which are pivotally mounted at their outer ends to the members I2 and I3. A rod 30 connects with each of the toggles and extends outwards and continues into a connecting section 3U which in turn is connected with an arm 3| pivotally supported at its far end 3I upon a bracket 32 mounted on the base plate I9.

Intermediate of the ends of the arm 3| 9. cable 33 is pivotally connected therewith. This cable extends downwards over guiding pulleys 34 and connects with a foot pedal 35 which is hingedly connected upon the floor. This foot pedal may be manually depressed to draw the cable, which in turn pivots the arm 3| downwards. This motion is transmitted to the toggles I4 which draw the notching elements I2 and I3 together and simultaneously move the notching elements downwards into operative positions. Pins 36 These vertical posts I8 project from the members I and H and limit the inward pivoting of the notching elements as indicated by the dot and dash lines in Fig. 4.

Pressure is applied to the member 30 causing the members l2 and 13 to pivot until the notching pins 25 engage the sides of the die I6 which acts as a guide, and prevents the members 12 and 13 from pivoting further. Pressure still being applied the members l2 and 13 no longer pivot so the pressure is then utilized to force the members I0 and Il down forcing the notching pins 25 to punch V-shaped notches in the collar and they then slightly engage into the opening in the die l5. When the pressure is released the springs 20 force the members back to their original position. The members I2 and I3 are pivotally mounted so that they swing into an inoperative position when it is desired to stamp the collar out by using the die 16. If it were not for this mounting the members 25 would be in the way of the die It rendering the device inoperative.

While pressure is being applied to lower the pins 25 and the die section IS the material from which the collar is being formed is manually held in a taut condition across the opening in the die section l to prevent the aforesaid elements from forcing the material into the opening.

The upper die section I6 is supported by an arm 38 which is attached to the top of the die section and continues into an upward extending portion 38, which in turn continues to a rearward extending portion 38 which is attached at its end to a bracket 39 mounted upon the base plate [9. A cable 40' is connected intermediate of the ends of the portion 38 and extends downwards over guiding pulleys 40 and connects with a foot pedal M which is pivotally mounted from the floor. When the foot pedal 4| is depressed the cable will be drawn and the motion trans mitted to ultimately move the die section l6 downwards to engage into the opening in the die section l5. The die section is normally urged into a raised position by a spring 43 coaxial upon 7 a rod 44 mounted upon the section 38 and guided by an opening 45 extending through the bracket 39. The spring 43 acts between the bracket and the section 38*.

The die section I5 is formed with slots 48 at the sides through which holding studs 49 projects. These holding studs may be loosened and the die section shifted as required, or the die section may be entirely removed. The die section I6 is shown in plan view in Fig. 1 and it should be noted that it is of a shape to include both the back portion and the front portion of a collar. The complementary die section I5 is of a cooperating shape. These die sections are adapted to stamp out a collar 50, as indicated in Fig. 6. The notching pins 25 form the notches 5| in the edges of the blanked out collar piece.

Fig. '7 shows a modification in which the blanked out collar section till is merely one of the layers of a collar. This collar section is shown formed with notches 5!.

In Fig. 8 a modified form of die is illustrated which is adjustable to produce collars of difierent sizes, for example, from size 14 to 17. The bottom die section is provided with a plurality of removable end pieces 52 and 53 which may be removed to increase the size of the opening in the die. Similarly, the complementary die section may be provided with similar pieces which may be added and removed as conditions warrant.

The operation of the device is as follows: Ma-

terial from which the shirt collar band is to be stamped is placed upon the bottom die section IS. The foot pedal 35 is depressed to cause the notching elements I2 and I3 to descend so that the notching pins cut notches in the material. The pedal 35 is released and the notching elements I 2 and I3 will move up to their normal position. The pedal 4| is then depressed which moves the die section [6 down to stamp out the collar band. It should be noted that in the stamped out'collar band the notches 5| are within the edges of the blank.
